As in (JUNIOR, ALENCAR e JOHN, 2011) and (A proporção de habitantes por carro nas capitais, 2016), the extensive increase in the fleet of vehicles in urban centers brings the challenge of parking several vehicles in confined spaces. A possible solution to this problem is the development of high-tech parking systems capable of parking multiple vehicles in limited spaces. The current thesis presents a solution to this problem and consists of developing a parking duplicator device that allows parking two vehicles in the space required to park only one. The solution is to lift one of the vehicles so that the other one can occupy the space below it. The device’s development was achieved by means of stress-strain analysis and CAD/CAM techniques. First, the design characteristics of the parking system were defined, and a conceptual design was developed. The structural analysis was then performed. The obtained results were used in the dimensioning of the elements determining its dimensions. Next, the solutions were refined through finite element analysis. Finally, a virtual prototype and a detailed project were developed mainly in the software SOLIDWORKS® v. 2019. And a reduced scale prototype was 3D printed. The obtained structure was a simple and inexpensive solution optimizing the parking system. The proposed device presents simple and innovative configuration and drive (with movable pulley) besides the characteristic of being able to be easily manufactured and assembled in series, which provides lower final cost of the product and characterizes it, along with its other attributes, as a great invention compared to the similar equipment currently available on the market, hitherto patented or in the state of the art.
